T '0 all to hem it may concern:

lie it known that I, Jaeon S. Barman, citizen of the United States,residing at Kansas tity. in the county of Jackson and State offitissonri, have invented certain new and useful improvements intonibined Grain- !)oors and Car-Doors, of which the following aspecification.

My invention relates to a combined grain and car door; and one of myobjects is to provide a door whicn will perform the double function of agraiindoor and an ordinary candooi'. so that each side of a car needonly he provided with one door instead of two as is (cu tomary when theear is equipped for hauling grain.

Other objects of the invention will hereinafter appear, and in orderthat it may be tally understood. reference will now be made to theaccompanying drawings, in Whieh:

Figure 1 represents a broken side elevation of a box-car equipped. withmy improved door. the latter being in a closed position. Fig. 2 is avertical central section on line li ---llt oi Fig. 1. Fig. 3 is a detailcroas seetien'of the door-jambs of the ear and my improved door, thelatter being partly disengaged from the former preparatory to openingthe door. is a broken side elevation of the (fit-i with my improved doorin an open position. Fig. 5 is a cross section on line V--V ot'i ig. l.

1 designates" a box-car provided at its sides with doorways 2.

3 designates a pair of door-jainhs at oppo site sides of each door my.Said doorjanihs are made oi sheet-metal having veriieal pockets 4pressed therein to receive the vertical edges of the. door, as showninFig. 5.

(i designates my improved door, which consist (it a ma n section 7 and apair o't flaps which latter are secured to the vertical sides of themain section by it and adapted to swing' inwardly as shown in Figs, 3-3and 4 to permit the door to open. The tree edges of tlaps 8 are taperedat their upper portions 10 so that said edges maybe more readilyinserted in pockets et when closing: the door.

Section 7 of the door is provided at its upper portion with an opening11, which is normally closed by a Wicket 152 secured by hinges 13 tothe. upper side of raid ening;, through which latter the car may hetilled \vith grain when the door is in a closed tion.

Door 6 is suspended from a pair of hangers H. each of whieh consis'a ofa hood 15. a hrack t it; seen red to the upper portion of section T, anda lint; I? pivotally connected. at its ends to the underside of hood toand the up er side of bracket 16 so that: section 7 n'iay swing outwardto the position shown in Fig. 3, prepa atory to opening the door.

Hood is provided with a pair of grooved rollers 18 arranged to travelupon a traek l9 suitably 'zeured to the upper portion of the ear. Saidtrack is circular in rro as-seetion so that the 'JOOVQtl rollers mayrock laterally thereon and permit the lower portion of the door to swingoutward as ndicated by the dotted lines a. Rv suspending the door inthis manne it i evident that the instant it is unloel immediately forcedoutwardly by the grain within the ear hence there \vili he no necess tyto employ a ertnvhar or other inzple lneut apt to injure the door inopening; the

same. t

The door is locked in closet position to transverse bar 20 engagingpoiets pivotaliy secured, at its eentrat t sectimi T by a holt fit. Ti 3are rounded so that when. tin heveled sides t ot the l said togetherwith the door Wili i) need inward and press flaps 8 ti htly against theinner sides t" of the pockets to pro cage of grain at these points.

The pivotal inovenn-nit of harhy a pair of loops seei'tred to sectionand when, it is desired to .toelt the car, sai bar is held in ahorizontal position, see l. by a latch 23 pivoted to the door andrevided with a eurved upper end i t to pass throng: i s the nut the hat.provided with a apl'- V 1 hen dosired the Wire of a there through andaround the adgacent loop 22, as Will he readiiy understood.

26 designates a handle secured to the lower portion of section 7 tootter a convenient. grip When opening or closing the door.

27 designates av retaining ip secured by a hinge 28 to a strip 29 forthe purpose of forming a grain-tight joint between the lower edge of thedoor and the threshoid of the doorway. Said retaining-strip may 2G islimitedt, l l

it Will he held against thelower portion of door 6 by any suitablefastening device, a pin 30 pass ing through a staple 31, being shown. Pm30 is secured from loss by a small cable 32 attached to handle 2".Staple 31 is secured to the lower portion of the door and extendsthrough an opening in the retaining-strip, as shown in Fig. l.

When it is desired to open the door, pin 31 is removed from the stapleand the retainirig-strip 27 is lowered to the position shown in hi g. 1.Latch 28 is then swung out of engagement with the lower end of bar 20 sothat the latter may swing on its pivot to disengage its extremities from"the pockets 4-.

1f the car be loaded with grain the pressure thereof will force the doorto swing out-- ward at its lower end, as hereinbeifore described, but ifit be loaded with merchandise;the door can be pulled outward bodily toclear the doonjambs and the side oi" the car. When the door is pulled.out in this manner links 17 turn on their pivots so that the door may beslid backward to uncover the doorway without interfering with the sideof the car, the foremost flap being previously foldedback against theinner side of sections 7 indicated by dotted lines, Fig. 4, to reducethe distance at which the door need be pushed backward to fully uncoverthe doorway 2. The backward movement of the door'is limited by a stop 33secured to the side of the car.

Having thus described my invention, what i. claim I i. A. car-doorconsisting of a main section and pair oi flaps hinged to the verticaledges thereof, metallic .door-jarnbs at the sides of the car door-wayhaving "sockets to receive the free edges of the laps, said ochetshaving beveled sides, and means for ocking the door in a closedposition, the

extremities of said means being arranged to enter the pockets and engagethe beveled sides thereof.

A car-door consisting of a main section 'and a pair of flaps hinged tothe vertical edges thereof, door-jambs at the sides of the car-doorwayhaving pockets to receive the free edges of said flaps, said pocketshaving beveled sides, and a bar pivoted to the main section of the dooradapted to engage the beveled. sides of the pockets, substantially asdescribed. I

3. A car-door consisting of a main section and a pair of flaps hinged tothe vertical edges thereof, door-j ambs at the sides of the car-doorwayhaving pockets to receive the free edges of said flaps, said pocketshaving beveled sides, a bar pivoted to the main section of the dooradapted to engage the beveled sides of the pockets, and a latch pivotedto the door for securing said bar in a locked position.

A car-door consisting of a main section and a pair of flaps hinged tothe vertical edges thereof, door-jambs at the sides of the car-doorwayhaving pockets to receive the free edges of the flaps, said pocketshaving beveled sides, means for locking the door in a closed, position,the extremities of said means being arranged to enter said pockets andengage the beveled sides thereof, members for carrying the door, andmeans pivoted to the door and said members whereby the door may swingoutward. bodily to disen its flaps from the pockets.

in testimony whereof I afiix my signature in the presence of twowitnesses. JACOB S. BENDER.
